# Video Generation Alias

> POST /v1/video/generations compatibility alias for clients that already depend on this video-generation path

# Video Generation Alias

```
POST /v1/video/generations
```

This is a Crazyrouter compatibility alias for clients or middleware that are already pinned to the `/v1/video/generations` path.

## Authentication

```http theme={null}
Authorization: Bearer YOUR_API_KEY
```

## When To Use It

* your client is hardcoded to `/v1/video/generations`
* you are migrating an older video workflow and do not want to change the path
* you need to preserve compatibility with an existing third-party request shape
* you want to submit Wan text-to-video models such as `wan2.5-t2v-preview` or `wan2.2-t2v-plus`

For new integrations, prefer:

* Wan text-to-video: use this page's `POST /v1/video/generations`
* Veo / unified-video workflows: use `POST /v1/video/create` with `veo-3.1-fast` or `veo-3.1-quality`
* OpenAI-compatible video workflows: use `POST /v1/videos`

## Minimal Request Example

### Wan 2.2 T2V Plus

```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/v1/video/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "wan2.2-t2v-plus",
    "prompt": "A calm cinematic shot of clouds over mountains",
    "seconds": "5",
    "size": "480P"
  }'
```

### Generic Minimal Example

```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/v1/video/generations   -H "Content-Type: application/json"   -H "Authorization: Bearer YOUR_API_KEY"   -d '{
    "model": "wan2.5-t2v-preview",
    "prompt": "A cinematic shot of waves hitting a cliff at sunset"
  }'
```

## Typical Success Response

```json theme={null}
{
  "id": "video_task_abc123",
  "task_id": "video_task_abc123",
  "status": "processing",
  "status_update_time": 1709123456
}
```

## Error Response Verified Locally

On the local `http://127.0.0.1:4000` environment, this route was verified to exist. When the model is temporarily unavailable, it returns a business error rather than `404`:

```json theme={null}
{
  "code": "get_channel_failed",
  "message": "model wan2.2-t2v-plus is temporarily unavailable, please try again later",
  "data": null
}
```

## Notes

* request fields vary by video model and upstream capability
* model availability depends on the token whitelist and current upstream state
* Wan text-to-video uses `model`, `prompt`, `seconds`, and `size`; the verified `wan2.2-t2v-plus` combinations are `seconds: "5"` with `size: "480P"` or `"1080P"`.
* Do not submit `wan2.2-t2v-plus` to `/alibailian/api/v1/services/aigc/video-generation/video-synthesis`.
* after task creation, query status with `GET /v1/video/generations/{task_id}`

<Note>
  This route is a compatibility alias. It does not guarantee that every video model shares the exact same body schema. Wan text-to-video currently uses this route; Veo and unified-video workflows should use `/v1/video/create` with `veo-3.1-fast` or `veo-3.1-quality`.
